My first reaction was WTF?! until I thought about it. You get your favorite music tattooed on, your girlfriend’s name, brands, formulae… and at least until complete number portability happens, your facebook username is one of the few permanent things in life.

…and the next time you wake up, clutching your head and wondering what the f happened after the thirteenth drink, and realize there’s someone else fast asleep next to you and you have no clue who… you can just do a quick once-over, and do a FB lookup long before she wakes up.
